For example they have developed an ant apparatus that uses microscope "antennas" on your hands to transmit a 50-fold magnified view of wherever your hand is resting. Watch their promo video:

As you can see, they've also developed a head-mounted solenoid compass that's supposed to provide a bird's sense of a direction. There's also a cool child to adult converter, which lets a kid see the world from an adult's height and speak in a deeper voice. I would have loved that when I was 10.
